IE Compatibility modes

This site is not supported in the old Internet Explorer compatibility modes.

Confirm the document mode by opening the debugging tools: press F12 and check the "Document Mode".

Browser zooming

Page zooming inevitably presents rendering artifacts in some components, both on this site and the rest of the web. Depending on the issue, we may be able to fix it (search first and then open an issue if need be). However, we tend to ignore these as they often have no direct solution other than hacky workarounds.

Printer viewports

Even in some modern browsers, printing can be quirky. In particular, as of Chrome v32 and regardless of margin settings, Chrome uses a viewport width significantly narrower than the physical paper size when resolving media queries while printing a webpage. This can result in Bootstrap's extra-small grid being unexpectedly activated when printing. See #12078 for some details. Suggested workarounds:

Embrace the extra-small grid and make sure your page looks acceptable under it.

Customize the values of the @screen-* Less variables so that your printer paper is considered larger than extra-small.

Android stock browser

Out of the box, Android 4.1 (and even some newer releases apparently) ship with the Browser app as the default web browser of choice (as opposed to Chrome). Unfortunately, the Browser app has lots of bugs and inconsistencies with CSS in general.

Viewing Tips

This site is designed to be compatible with most browsers on the Windows/Linux platform, but we recommend specific configurations. Many older versions of these browsers do not support the latest Internet technology (such as DHTML, style sheets, JavaScript, SSL security or frames).

By using the recommended configurations, you will be able to take advantage of all the site's features. Although your browser may not be listed it may still work. However, using unsupported configurations may make certain features unavailable.
